Nen

Nen (nŭn) [key]or Nonni (nôn'nē) [key], river, 740 mi (1,191 km) long, rising in the Yilehuli (Ilkuri) Mts., N Heilongjiang prov., NE China, and flowing south along the east side of the Da Hinggan (Great Khingan) range to the Songhua River; forms part of the Heilongjiang-Jilin provincial border.
